To make this improvisation one needs a fretless strings isntrument like a ud, cello, viola, violin etc
The one must kow the 3 basic ancient greek music 4-chords
1) The diatonic gendre 4-chord which is in semitone intervals the pattern 2-2-1 (and all permutaions of it)
It is suposed to reflect balanced feelingsof joy or sorrow
2) The enharmonic gendre 4-chord which is in semitone intervals the pattern 4-1/2-1/2 (and all permutaions of it)
It is suposed to reflect feelings of joy. The 1/2 semitone in the cello fingerboard is about one mail finger width
3) The chromatic gendre 4-chord which is in semitone intervals the pattern 1-3-1 (and all permutaions of it)
It is suposed to reflect feelings of sorrow.
When we improvise we just put consecutivlly a repetitive combination of the previous 3 patterns
(2-2-1), (1-3-1), (4-1/2-1/2) in which ever combination and permutation our feelings indicate.
Each 4-chord can be played with our 4 fingers of the left hand.
Of course we may improvise as well with chord-terrachords, in other words 4 notes having totla sum in intervals a pure 5th (7 semitones) and including 3 notes of minor , major chord. See post 325
E.g. the next 10 4-chords:
major: 2-2-3
minor: 3-2-2 ,
major 4-1-2 ,
major 4-2-1 ,
minor 3-3-1 ,
minor 3-1-3
major 3-1-3 ,
major 1-3-3 ,
minor 2-1-4 ,
minor 1-2-4
